As Eli and Stefan have pointed out, this isn't likely to gain
performance due to the global lock.

I wanted to point out, though, that it is possible to lock a process to
a thread.  (info "(elisp) Processes and Threads")  So part of what you
want is there.

I think it would be good for Emacs to experiment with less cooperative
thread scheduling.  This came up before and was rejected; I should have
spoken up then, since my view is that this really isn't all that
dangerous, because in practice there just aren't that many threaded
programs.  Also, this is a necessary step toward true multi threading.
